The Best Fertility Lubricant For You

When you are trying to conceive it is vitally important that couples use a sperm friendly lubricant rather than a regular lubricant, such as KY Jelly, when making love. Clinical studies have shown that the use of regular lubricants when trying to conceive is not advisable. Many vaginal lubricants have been found to inhibit the conception process or to have no positive effect at all. That is not to say that you can’t get pregnant using common lubricants but your chance of success may be lowered. At their worst, regular lubricants may even kill sperm!

So which lubricant should you use? At Zoom Baby we stock all three of the leading pre-conception lubricants on the market in the UK today.

All of the lubricants we offer have undergone extensive laboratory testing and are sperm friendly! We can recommend them all. Which one you choose really comes down to personal preference.

Conceive Plus

Conceive Plus is a sperm friendly lubricant that is manufactured by a company called Sasmar. It claims to be the only fertility lubricant that can proactively aid your chances of getting pregnant.

The formula for Conceive Plus contains both magnesium and calcium ions. These ions combine to help keep sperm healthy and viable and also help to enhance their motility, which is their ability to swim. Conceive Plus has also been shown to be beneficial if you have been experiencing vaginal dryness when trying to conceive.

Suitable for all couples who are trying to get pregnant, Conceive Plus can also heighten pleasure during sex, enhancing both your enjoyment and your chances of getting pregnant naturally.

Conceive Plus is available in a multi-use tube or as individual applicators. The individual applicators work out a bit more expensive than the multi-use tube. We currently sell the eight applicator pack which will offer one month’s worth of lubricant. The multi-use tube is a more economical buy and can currently be bought in 30ml and 75ml versions.

Conceive Plus reviews are generally very positive, which is why it is the first choice for many couples who are trying to conceive. We offer extensive instructions on how to use Conceive Plus and full information is also included in each pack.



Pre-Seed (aka PreSeed)

Pre-Seed Fertility-Friendly Lubricant was invented by two women reproductive physiologists in 1994. Pre-Seed claims to offer mild moisture for every day lovemaking and vaginal comfort.

Pre-Seed was developed specifically to match a woman’s fertile fluids and to provide safe lubrication for use when trying to conceive a baby. It is formulated so that it has an identical pH and osmolarity to male semen. This means that it won’t harm sperm. It also allows pre-seed to be mild for a woman’s body.

Pre-Seed is sold in a 40g tube, along with nine applicators. Pre-Seed’s applicators can help increase comfort during intimacy by coating the entire vagina in the same way that body fluids do.

Reviews of Pre-Seed are always really positive from our customers. One main reason for the popularity of Pre-Seed is that is really easy to use. We offer instructions on how to use Pre-Seed on this website and fully information on using Pre-Seed is also found in each pack.


FertilSafePLUS has been developed by Babystart, one of the world’s leading providers of fertility In Vitro Diagnostic (IVD) products and fertility supplements.

Standard lubricants can work against the natural fertilisation process by damaging sperm or hindering the movement of your man’s little swimmers. FertilSafePLUS does not cause these problems. This lubricant ensures the ideal pH and consistency for natural conception. This protects sperm and preserves their motility and viability. This makes FertilSafePLUS and ideal lubricant to use when trying to conceive.

FertilSafePLUS is paraben and glycol free. It has been clinically tested by a expert UK clinic within the NHS, to proving that it is perfect to use when trying to conceive.It is available as a 75ml tube or as a multi pack which also contains two small individual tubes of lubricant and two applicators.

More details on pH levels and sperm health: When trying to conceive, the vaginal pH level is very important. The normal vaginal pH is between 3.8 and 4.5. This acidic environment protects the vagina from infections. However, semen is alkaline, with a pH between 7.2 and 8.0. This alkaline pH helps neutralize the acidic vaginal environment and protects sperm. If a lubricant is not pH-balanced for fertility, it can harm sperm. The lubricants recommended in this article all have a sperm-friendly pH that will not disrupt the delicate pH balance needed for conception.

Extra tips for maximising fertility: Along with using a fertility-friendly lubricant, there are other tips couples can follow to increase their chances of conceiving:

Signs it may be time to see a fertility specialist: Most couples will conceive within 6 months to a year of trying. But if you are under 35 and have not gotten pregnant after a year of well-timed unprotected sex, it may be time to have a fertility workup. Some signs to look out for:

  • Irregular menstrual cycles
  • Confirmed ovulation problems
  • Endometriosis or PCOS
  • Previous pelvic infection
  • Uterine fibroids or structural issues
  • Male factor infertility such as low sperm count

Seeing a fertility specialist early can help identify any issues and improve your chances through treatments like ovulation induction, IUI, or IVF.
